J. A. NORRIS, OF PHILADELPHIA, PENNSYLVANIA.

JOURNAL-BOX.

Specification of Letters Patent No. 20,383, dated May 25, 1858.

To all whom it may concern:

Be it known that I, Jas. A. Norms, of Philadelphia, in the county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Boxes for Shafting and other Journals; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in constructing the box or bearing in which the shaft runs with glands and stuing boxes, as hereinafter fully described, whereby the passage of any dust or injurious substance to the interior of the box is rendered impossible; also in packing, the sides for the same purpose.

In the accompanying drawings, forming part of this specification, Figure l, represents a front elevation of my improved box carrying a shaft; Fig. 2, a back elevation of the same; Fig. 3, an end view; Fig. 4, a top view; Fig. 5, a vertical section, on the line w, ai', at Fig. 4l; Fig'. G, a vertical section on the line 3, 3, at Figs. l, and t; Figs. 7 and 8, detail views of gland, and Fig. 9, a similar section to Fig. 6, showing the variable packingfsimilar letters denoting the same parts in the different views.

A, Arepresents the upper and B, the lower half of the box, which supports, and in which runs, the shaft C. In the upper portion A,of said box, is formed an oil chamber L,-by making an enlargement as seen at c,-into which the lubricating material is put through a suitable aperture g, in the top of the enlargement c, furnished if necessary with a lid or cover'. The lower portion B, of said box has formed upon its back side, and extending upward, an arm B, of any desirable shape which is intended to serve the purpose of a hanger, and the two portions A, and B, are so constructed, as that, when they are clasped around the shaft, C, and secured in their proper relative positions (which is done by means of ordinary bolts, f, f, and suitable flanges or ears on the said portions of said box) there shall be found in each end of the box a cylindrical cavity, around the shaft, @,-or technically, a stufling box to accommodate suitable packing7 material, (as seen at Fig. 5 in the drawing) z', z'. &c., and which are furnished with glands D, D, &c., adjusted in and secured in proper relative position to said stutling boxes, by suitable bolts E, E, L-c., projecting from the upper and lower portions, A, and B, of the box, and furnished with nuts (as shown in the drawings).

The peculiar construction of the glands D, D, &c., will be best comprehended by reference to the different views thereof represented in the drawings, from whence it will be readily observed, that the gland, adapted to the stu'liing box in either end of the box, is formed of two parts, marked, D, D, each of which parts is furnished with two ears, (Z, cZ, and holes therein, to accommodate bolts, or screws, e, e, by means of which ears and bolts the two parts, of said gland are united, causing their semi-cylindrical shell to forni a perfect cylindrical shell, around the shaft C, and adapted to the stuffing box in the end of the box. At Fig. 7, the portions D, D, are represented as being detached, and withdrawn from around the shaft C, while at Fig. S, they are shown as being united around said shaft; as also at- Figs. 3 and 5, &c.

The upper and lower portions, A, and B, of the box are so constructed, (see Fig. 9,) that when secured around the shaft o, with their bearing surfaces, in contact with the saine, their adjacent surfaces shall not come in contact with each other, but shall remain some distance apart leaving a space occupied, with leather, or other, packing, 0, (see Fig. 9,) and in contact with which packingl the adjacent sides of the said portions, A, and B, are brought and retained. This packing may be composed of thin layers, of leather' or other suitable material, in order that as the box wears away, or that portion of it which forms the bearing surface for the shaft, (which wear is mostly downward, from the weight of the shafting) the upper and lower portions maybe brought nearer together, and again in contact with the shaft, by simply removing a layer or so of the said packing, 0, and turning down the bolts f, f, &c. V

The two parts D, and D', of the glands. are also, so constructed, that, when united around the shaft, o, they shall embrace between thein (in like manner to the two portions. A, and B, of the box) a packing. `i'. (see Fig. 8) which capable of reduction.` in thickness, and the layers of which are withdrawn, when and in the same ratio as. those of the box are extracted. If deemed expedient, when the bearing surfaces of the box and glands become worn, the packings, o, and, r, of the former and latter may be entirely removed and the bearing re-bored.

The details, of my improved box, it is obvious may b-e varied without changing its features of novelty and ability, or losing the main features of construction upon which depend its advantages and perfect operation, which latter, I will now explain and which will be readily understood from what has already been said of its construction.

The lower portion being' placed (in the proper position) beneath, and having its bearing surface in contact with, the shaft, C, or supposing the said portion, B, already suspended and secured in place by its hanger or ar1n,B, and the shaft, C, placed in said portion, making its relative position with the latter, such as before described, the upper part A, is placed over said shaft, C, and portion, B, as shown in the drawings, having first had placed between it and the said lower portion, the requisite amount of packing, 0, and is secured to the portion, B, by bolts f, f, j', f. The parts D, D, of the glands are then placed one above and the other below, the shaft (as seen in the drawings) with the requisite packing, @between said parts D, and D, and are united and se-y cured by their respective bolts e, e, e, e, and ears, d, cl, cZ, CZ', when the said glands, are run, on the shaft, C, into, their respective stuiiing boxes, formed as before described; the said stuiiing boxes having been furnshed with suitable packing, z', z', and are adjusted and secured therein by the bolts E, E, &c., passing through them, and furnished with nuts, as before described. The parts having been all thus relatively placed and secured together, the clamping pressure, coming upon the packings, 0, and, r, the bearing surfaces of the box come in contact with the shaft, C, without creating any more friction than is actually necessary.

The great advantages arising from the construction of boxes, for shafting, as above described, are-iirstly, a perfect retention of the oil or other lubricating material, bestowed upon the shaft where it coines in contact with the box; secondly, its preclusion of all dust, or other injurious matter to the bearings.

Having fully described the construction of my improved gland box for shafting and explained its operation, what l claim therein as new and desire to secure by Letters Patent of the United States is l. The combination of the glands D, D, &c., with a box A, having stuffing boxes formed in each end; substantially as and for the purpose herein described. Y 2. Arranging a packing, 0,.between the adjacent sides of the box as described whereby the entrance of any dust between said sides is rendered impossible.

In testimony whereof I have hereunto set my hand this eighth Vday of April 1858.

JAS. A. NORRIS.
